A series of 1,3,4-thiadiazole derivatives containing 1,4-benzodioxan (2a–2s) have been synthesized to screen for FAK inhibitory activity. Compound 2p showed the most potent biological activity against HEPG2 cancer cell line (EC50 = 10.28 μg/mL for HEPG2 and EC50 = 10.79 μM for FAK), which was comparable to the positive control. Docking simulation was performed to position compound 2p into the FAK structure
合成了一系列含有1,4-苯并二恶烷(2a - 2s)的1,3,4-噻二唑衍生物,以筛选FAK抑制活性。化合物2p对HEPG2癌细胞系表现出最有效的生物学活性(HEPG2的EC 50 = 10.28μg/ mL ,FAK的EC 50 = 10.79μM),与阳性对照相当。进行对接模拟以将化合物2p置于FAK结构活性位点,以确定可能的结合模型。抗增殖和蛋白质印迹试验的结果表明,化合物2p对HEPG2癌细胞系具有良好的抗增殖活性。因此,化合物2p 具有强FAK抑制活性的化合物可能是针对HEPG2癌细胞的潜在抗癌药。
